To all whom it may concern: Beit known that we, PEnoY W. POMERQY UnitedStates, residing at Toledo, in the countyof Lucas and State of Ohio,have in vented certain new and useful Improvements in AutomobileHeadlights, of which we declare-the following to be a full, clear, andexact description.

This invention relates to improvements in headlights and. particularlyto headlights of the type which the refiectoris pivotally mounted withinthe casing so that it maybe tilted to direct the beam of lightdownwardly uponthe ground in front of the ve-' hicle at such an angle asto'elmin'inate such glaring as would be objectionable to an approachingdriver or pedestrian.

. The principalobject 0 f our invention is to provide animprove'dpivotal mounting .for the reflector, in which the reflector ispivotally-supported' at'a single point at the rear of the reflector. v

Further objects of 'this invention "relate to economies ofmanufactureanddetails of construction as will hereinafter appear fromthe detailed description" to follow. We accomplish the objects of ourinventionin one instance by the devices andmeans described in thefollowing specification, but it is evident that the same may be. variedwidely without departing from the scope of the invention as pointed outin the appended claims. A structure constituting one embodiment of ourinvention, which may be the preferred, is illustrated in theaccompan'yin'g drawing formingia, part hereof "in .Which:-

carried by the casing 10 and connected by, wires 25 with the socket 20,said wires pass- T In the drawings, similar reference' numeralsrefer tosimilar parts throughout the several views and the sectional view istaken ,vided'within the casing, the forward edge of 'said reflectorbei'n rolled backto form a stifi'ening bead or of the casing 10,extending inwardly in line with the axis of the casing and thereflector,

the' sleeve and the casing] being co-'axial.

The forward end of said sleeve is enlarged to 'form a socket 16'. Aball17 is secured to the rear end of thereflector 13 bymeans of the flange18, said ball being co-axial with the reflector and being normallydisposed in the socket 16, said ball and socket being concentric. Asleeve -19 is carried within the ball 17 andla-s ocket "20 is disposedwithin said sleeve, .saidisocket being provided with 2. lug 21 disposedin a slot 22 formed in the sleeve '19, so as .to prevent the socketturning relativeto the sleeve. The socket 20 receives the electric lightbulb A connector 24;. is

in throu h slots 29 and 30 formed in the ba 1 17 an socket 16respectively. An opening 26 is provided in the upper part of the sleeve15, as show'n in Figure III, and the .socket' 1.6 is also provided-witha slot 27 ange 14: A sleeve or. tubular support '15 is secured to therear-end in which a lug 28 struck up from the ball 17 is disposed.-

A lug 31 is provided onfthe reflector near the forward edge thereof andconnected with a lug 32011 the casing 10 by a spring near the forwardedge thereof and substanlug 34. Pins 36 and 37 are secured to the wire35 and serve as stops to limit the throw thereof in a, mannerwhich-willpresently-be described. -The wire 35 movesin a tube 38 whichis secured in'a boss'39, carried by the casing 10, by means of a setscrew 40. The

. boss 46 is rotatably mounted in the disc if of the tube 38 so as tolimit the movement of the wire. The wire may be. moved to effect atilting of the reflector in any suitable manner.

An opening is provided in the rear of the headlight casing 10 in linewith the sleeve 15 and said opening is closed by a cover 11 which ispivotally connected at 12 to the casing and which is held in closedposition by the engagement .of the hub 43 with the depression 414 formedin the cover 41. A screw 45 extends rearwardly from the socket 20 and acarried by the end of the sleeve 19, said boss 16 having ascrew-threaded engagement with the screw 45.

From the description oftheparts given above, the operation of thisdevice should be very readily understood. The reflector is shown inFigure ll in full lines in the position in which it throws a horizontalbeam of light. When itis desired to deflect the beam of light downwardlyupo-n the ground, the wire 35 is pulled until pin 36 engages the end oftube 38. This movement will bring the reflector to the position shown,in dotted lines in Figure I against the tension of the spring 33. Thereflector is supported by and pivotally mounted by the socket 16 at theforward end ofthe tube .15 and the ball 17 carried the rear endof thereflector turns in said socket. The turning movement of the ball 17 inthe socket 16 is limited by the engagement of the tongue 28 in the slot27 formed in the socket. The sleeve 15 is cut away at 26 so that the endof the sleeve 19 may swing up into this opening so as to permit theparts to have the necessary angular movement relative to each other.After the wire 35 has been manipulated to throw the reflector to thedeflected position, it is preferably latched in this deflected positionand, when the latch 1s released, the spring 33 will return the reflectorto its normal position. The limits of movement of the reflector may bedetermined by adjusting tube 38 within the boss 39 by loosening the setscrew 40, but the extent of movement remains the same in all cases,being determined by the distance between the pins 36' and 37 The lightmay be focused. by swinging to one side the cover i the spirit thereof,and therefore we desire to claim our invention broadly, as well asspecifically, as indicated by the appended claims.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is:

1. Tn a device of the class described, the combination of a casing, areflector pivotally mounted at the rear thereof within saidcasing, meanstending to move said reflector in one direction, and means connected tosaid reflector to move it in the opposite direction.

2. In a device of the class described, the combination of a ,casing, areflector therein having a light source, a reflector support secured tosaid casing, a hollow member car-.

' by said reflector is pivotally supported from said casing, a lightsource, and means for tilting said reflector in said casing withoutvarying the focus of said light source.

4:. lln a device of the class described, a casing, a reflector pivotallymounted therein, the pivotal mounting for said reflector being at therear of and in the axis of said reflector, a light source carried bysaid reflector, means to adjust the focus of said light source in saidreflector, and means for tilting said reflector. i

5. lln a device of the class described, a casing, a reflector pivotallymounted therein, the pivotal mounting for said reflector being at therear of and in the axis of said reflector, a light sourcecarried by saidreflector, and means to adjust the focus of said light source in saidreflector, said means lying also in the axis of said reflector.

6. lln a device of the class described, the combination of a casing,asreflector, means for pivotally mounting said reflector in said casing,said means comprising a hollow pivot secured to one of said members anda pivot embracing member secured to the other of said members, and a lamsocket carried by said reflector and extending into said hollow pivot.

7. lln a device of the class described, the combination of a casing, areflector, means for pivotally mounting said reflector in said casing,said means comprising a hollow pivot secured to the rear of saidreflector, and a hollow support carried by said casing and embracingsaid pivot, and alamp socket rfor said reflector extending into saidpivot and support.

8; In a device of the class described, the combination of a casing, areflector, means for pivotally mounting said reflector in said casing,said means comprising a hollow pivot secured to the rear of saidreflector, and a tubular support secured at one end to said casing andflared at its opposite end 10 to 'embrace said pivot, andan adjustablelamp socket for said reflector extending rearwardly into said hollowpivot, said socket havin an adjusting screw at its rear end and saicasing having an opening opposit'e said tubular support to permit theinsertion of an adjustin tool.
